Abstract
A disconnection device is designed to separate a first portion of an electrical circuit electrically from a second portion of said circuit, the disconnection device including: at least one pair of contacts, one of which contacts is a moving contact, the pair of contacts having an open state and a closed state and a flexible conductor fixed at one end to the moving contact and serving to be fixed at the other end to one of the portions of the electrical circuit. The conductor comprises a flexible tube that is electrically conductive, at least at a surface portion thereof, and that has bending stiffness that is low enough to enable it to bend without kinking, and torsion stiffness that is high enough to enable it to take up a shape and a position that are substantially reproducible at least in the closed state. The device is used in particular in gas-insulated high-voltage electricity substations.
